Applications and Programming Models: "IWAVE to IWAVE++: from modeling to inversion," William Symes, Rice University


Watch the video


At last year's meeting, the author presented IWAVE, an open source package for synthesizing seismic data. This talk marks the release of IWAVE++, the migration and inversion package based on the IWAVE modeling engine. This first-ever open source inversion package includes a variety of optimization and modeling options and hooks for adding many more. Along with standard time-domain full waveform inversion and least squares migration applications, the first release of IWAVE++ also includes extended modeling and nonlinear differential semblance options. Biondo Biondi and his group recently used a nonlinear differential semblance algorithm to give a satisfactory solution of the Marmousi velocity-model building problem for the first time in its 20+ year history.
